If an error like the following one shows up after a social login:
An error occurred during Google Plus login to the site, error details: file_get_contents(https://accounts.google.com/o/oauth2/token): failed to open stream: no suitable wrapper could be found"
the problem could be due to php.ini settings on your server, not having requirements and the needed PHP libraries enabled.
In this case ensure to have enabled:
- PHP CURL library
- PHP socket support
